I don't realize those Showa SFF Air forks are the "triple air" forks with the canister at the bottom of the right leg AND 3 sealed off chambers????? I cant wait to see how they perform and you can get your ass Im gonna byuy a set off of Ebay ater the bike has been out for a year plus buying a stock set of these SFF Air forks will be cheaper than a revalve and the possibilities for adjustment are limitless. Plus im getting them for my 06RM250 so if they perform well on the 450 they are going to be an absolute dream to have on my 250 2 stroke. If they are as good as they look from an engineering standpoint they will be that much better on my much lighter 2 stroke. Of course they are 49mm so ill have to get the clamps too but other than that everything from the looks of it will be a slam dunk in fitting them to my bike. Suhhhh-weeeet!!!! Hopefully someone does the retrofit before me so I have a reference guide to follow hahaha
